    I have dealt with Jasper engines in used cars. If you like stock and boring then its for you. I have seen a 4.3 v6 from them last 130000 miles without an issue.

    I would look into a gm crate motor. You can get them at any gm dealer. usually cheaper than jasper and I think they are new not re-manufactured. They have a good warranty as well.

    Re: Jasper Motors?

    Kinda related. The guy that wheels with me that has the ZR2 Blazer just put a Jasper trans in. He loves it so far but it's only been in about two months. Soory bro, that's the only Jasper experience I've got.

    I got the roller 350 that is in the Chevelle from Pep Boys for around $1200. That was about 13 years ago though....

    my brother had a jasper 305 that he installed in one of his trucks about 8 or 9 years ago. he put probably 50-75k miles on it without a problem.
